Dr.Tim’s Aquatics Freshwater One & Only Nitrifying Bacteria – For New Fish Tanks, Aquariums, Water Filtering, Disease Treatment – Eco-Friendly Fish Tank Cleaner – Removes Toxins – Treats 30 Gallons

Was told about this ineint use nothing else

It didn't start working on few first days until after doing a little bit of research that I realized I needed some nutrients in my tank to provide enough energy for the bacteria to reproduce. The problem is my case was lack of enough phosphorus and magnesium in water. So, check your local water for traces of these elements if your fishless cycle has stuck and then add pinch of ground fish food into your tank in case of lacking of them in your fish tank water. Check your fish food to make sure it has these two before doing so. If you need more information, search for fishless cycle phosphate block and you'll find more information on this.

I was skeptical at first, having cycled tanks previously taking a minimum of a month i didnt think that this bacteria would do as advertised. However, i recently set up a small 60l aquarium, followed the instructions and less than 24 hours later my ammonia is almost nil. Nitrites still need to drop but usually takes at least 2 weeks for ammonia to drop to nil so already definately worth the money.

I have set up many new tanks over many years with the only additive being Aquasafe with no problems then I read about Dt Tims one and only which I used,as the instructions,after only a few hours the water became not cloudy but opaque,I could not even see the back wall of the tank and is still the same after a week! "You can put fish in straight away" This product certainly does not do "What it says on the tin"I dont think I will take the risk.

Did absolutely nothing. States you can’t overdose so on setting up a brand new 20l small tank I followed all instructions on there website, purchased Dr Tim’s ammonia as well, did everything step by step. The quantity I used of the live bacteria should have ensured great results, but absolutely nothing even though I’ve tested water daily since. Completely ineffective product and waste of money for me.

I've been trying to cycle my tank for months, so I bought this to try and speed it up. I put it in yesterday, when my readings were 0.5ppm for ammonia and light purple (not sure what that is) for nitrite after a 30% water change. Tested again tonight and it's roughly the same, which is pretty good seen as it's been a lot higher after a night of no water changes in the past. So far, it's looking like it's working! Just be prepared to have a lot of 'bits' floating around (I'm guessing this is the material they use to stick the bacteria to to transport it).

I tried bac bombs , biological enhancers and all sorts if other stuff whilst emergency cycling with a sick fish .. no2 n 3 n amonia just would not level fast enough . 1 bottle of dr Tims all at once levelled amonia a d no2 to 0 so fast i was amazed they didnt go back up either(make sure you watch the how to use video by dr tim on Youtube). Best stuff ever, will always have a bottle ready to in case of an emergency

This appears to be dead on arrival from amazon. I have ordered another bottle from an aquatics shop to see if there is a difference. API liquid tests showing 5ppm ammonia and 0ppm nitrite after5 days of daily testing.Update: This product does work well. I bought a second bottle from an aquatics shop and it has worked exactly as described. Over several days I've seen ammonia reduce, nitrite peak and fall off and nitrates building up. This clearly indicates beneficial bacteria have established in the aquarium.I can only assume as others have stated that amazon may not be storing the product correctly (either too warm or perhaps freezing) and therefore killing off the beneficial bacteria during storage.
